如何在jQuery中访问外部JSON数据文件？

Question

我试图使用下面的脚本在我的html文件中访问此文件，但它一直给我错误：

$.getJSON('https://(url of the file uploaded to file server is here)/data.json', function(data){

 //code goes here
})

当我在浏览器上加载文件时文件正在工作但是当我打开html文件时，我在控制台中收到此错误：请求的资源上没有“Access-Control-Allow-Origin”标头。因此不允许原点'null'访问。 我错过了什么？ 这是我的json文件：

[

            {
            "name":"United Kingdom",
            "countryCode":"GB",
            "urlCode":"en-gb",
            "standardPrice":"30",
            "standardFreeOver":"x",
            "standardTimes":"x",
            "expressPrice":"x",
            "expressTimes":"x",
            "collectionPrice":"x",
            "collectionFreeOver":"x",
            "collectionTimes":"x",
            "collectionPoints":"x",
            "imgName": "uk"
        },{
            "name":"Germany",
            "countryCode":"DE",
            "urlCode":"de-de",
            "standardPrice":"22",
            "standardFreeOver":"0",
            "standardTimes":"x",
            "expressPrice":"x",
            "expressTimes":"x",
            "collectionPrice":"x",
            "collectionFreeOver":"x",
            "collectionTimes":"x",
            "collectionPoints":"x",
            "imgName": "de"
        }
